Operation Instruction for the user and the qualied installer
2. First Operation
Before turning on the water
heater to start operation open all
of water valves fully at every point, so that
water is able to ow through the heater
and expel air from the pipe and the tank,
until the water ow is constant. Please
ensure that the water heater is functioning
correctly, and close the valve again.
WARNING:
When selecting an appropriate
water temperature, the temperature may
be dangerously high, especially for children.
Keep away from the hot water outlet, as it
may cause a potential scalding hazard.
- The indicator light will show.
- The DHCE.../50 Water Heater fea-
tures a temperature control knob at the
front of the unit, whereby 3 temperature
levels may be selected.
2.1 Adjusting Water Flow
If the required temperature is not
reached, you may adjust the ow rate by
turning the combination valve or water
ow control device (Fig. 2, No.12).
The hot water temperature
depends on the power of the
unit, the cold water temperature and the
ow volume.
This appliance is designed for
domestic use. It can be used safely by
untrained persons. The appliance can also
be used in a non-domestic environment,
e.g. in a small business, as long as it is used
in the same way.
